CVE-2026-97643 is a medium-severity vulnerability rated 6.4/10 on the CVSS scale. The GiveWP – Donation Plugin and Fundraising Platform plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's `givewp_campaign_grid` shortcode in versions up to, and including, 4.17.0 This is due to insufficient input sanitization and output escaping on user supplied shortcode attributes (`filter_by`, `layout`, `sort_by`, `order_by`) in the CampaignGridShortcode::parseAttributes() function combined with the render template emitting `json_encode($attributes)` inside a single-quoted HTML attribute without esc_attr() — json_encode() does not escape single quotes by default, so a `'` in an attribute value breaks out of the enclosing attribute. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.. EPSS estimates a 0.21% chance of exploitation in the next 30 days.
